Which of the following would cause an error in dna replication? a. helicase making a replication fork b. dna ligase taking apart chuncks of dna c. dna polymerase pairing c with g d. dna polymerase checking the dna

Ans.

Mistakes during DNA replication, such as addition of an incorrect nucleotide base in daughter strand or breaks in daughter strand that leads to change in nucleotide sequence of DNA, are known as DNA replication errors.

The enzyme DNA ligase repairs the breaks or irregularities in the DNA molecules, such as joining of Okajaki fragments. Therefore, defects in DNA ligase that take apart chunks of DNA would cause an error during DNA replication.

Thus, the correct answer is 'option B).'

i believe it's c. the trait for large beaks will be passed on to future generations through natural selection.

since eventually smaller beaks would have to find another source of food or even eventually just die out from the lack of food.
